Abstract
Abstract A strip-like part or cover for edge binding assembled pages to form a book-like assembly, the part consisting of a substrate such as paper bearing three stripe-like formations of heat activated adhesive on one side thereof. The central adhesive stripe is substantially thicker than the other two stripes, and extends along the substrate axis with a width approximately equal to the overall thickness of the book to be bound. The remaining adhesive stripes, which flank the central stripe are preferably comprised of adhesive having a relatively high tack when heated while the adhesive comprising the center stripe has a relatively low tack when heated to facilitate application of the binding stripe. As an alternate, the flanking stripes may be comprised of a pressure sensitive adhesive.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
183 words
Means for edge binding pages together in book fashion comprising: a substrate of formable material, said substrate having a minimum width greater than the thickness of the book to be bound to permit said substrate to overlay not only the book end but also at least that portion of the outer pages of said book immediately adjoining said book end; a first relatively thick heat activated low tack adhesive on one face of said substrate and substantially along the centerline thereof, said first adhesive being smaller in size than said substrate and arranged in a generally longitudinal stripe formation such that uncovered portions of said substrate project therebeyond at least along the sides of said first adhesive stripe; said first adhesive stripe being of a width sufficient to accommodate the thickness of the pages to be bound; and a second relatively thin adhesive on said substrate uncovered portions at least along each side of said first adhesive stripe whereby to form a pair of secoNd adhesive stripe formations flanking said first adhesive stripe, said second adhesive consisting of a relatively high tack adhesive.
Claim 2
Dependent Claim
183 words
Means for edge binding pages together in book fashion comprising: a substrate of formable material, said substrate having a minimum width greater than the thickness of the book to be bound to permit said substrate to overlay not only the book end but also at least that portion of the outer pages of said book immediately adjoining said book end; a first relatively thick heat activated low tack adhesive on one face of said substrate and substantially along the centerline thereof, said first adhesive being smaller in size than said substrate and arranged in a generally longitudinal stripe formation such that uncovered portions of said substrate project therebeyond at least along the sides of said first adhesive stripe; said first adhesive stripe being of a width sufficient to accommodate the thickness of the pages to be bound; and a second relatively thin adhesive on said substrate uncovered portions at least along each side of said first adhesive stripe whereby to form a pair of secoNd adhesive stripe formations flanking said first adhesive stripe, said second adhesive consisting of a relatively high tack adhesive.
Claim 3
Dependent Claim
61 words
The binding means according to claim 1 in which said substrate material has a length substantially equal to the length of the pages to be bound, the length of said first adhesive stripe being less than said substrate length whereby to provide open areas adjacent the ends of said first adhesive stripe into which said first adhesive may flow during binding.
Claim 4
Dependent Claim
23 words
The binding means according to claim 1 in which said first adhesive stripe is attached to said substrate material by said first adhesive.
Claim 5
Dependent Claim
29 words
The binding means according to claim 1 in which one face of said substrate material is entirely covered with said second adhesive, said first adhesive stripe being disposed thereover.
Claim 6
Dependent Claim
17 words
The binding means according to claim 1 in which said second adhesive comprises a heat activated adhesive.
Claim 7
Dependent Claim
17 words
The binding means according to claim 1 in which said second adhesive comprises a pressure sensitive adhesive.
Claim 8
Dependent Claim
43 words
The binding means according to claim 1 in which the width of said first adhesive stripe is less than the thickness of the pages to be bound, said first adhesive stripe expanding out when activated to accommodate all of the pages being bound.
Claim 9
Dependent Claim
28 words
The binding means according to claim 6 in which the activating temperature for said high tack adhesive is less than the activating temperature for said low tack adhesive.
Claim 10
Dependent Claim
22 words
The binding means according to claim 1 in which said first adhesive stripe is comprised of a series of spaced adhesive segments.
Claim 11
Dependent Claim
23 words
The binding means according to claim 9 in which said second adhesive covers the areas of said substrate between said first adhesive segments.
Claim 12
Dependent Claim
22 words
The binding means according to claim 9 in which said adhesive segments are attached to said substrate material by said first adhesive.
Claim 13
Dependent Claim
26 words
The binding means according to claim 9 in which said substrate one face is entirely covered by said second adhesive, said adhesive segments being disposed thereover.
Claim 14
Dependent Claim
135 words
An adhesive binding piece for use in edge binding pages together to form a book-like assembly comprising: a strip of formable substrate material; a relatively thick stripe of heat activated adhesive on said strip extending longitudinally thereof substantially along the strip centerline, said adhesive stripe being comprised of a relatively low tack adhesive; and a relatively thin stripe of heat activated adhesive on said strip on each side of said relatively thick low tack adhesive stripe and in boundary relationship therewith, said relatively thin adhesive stripes being comprised of a relatively high tack adhesive adapted on use of said binding piece to provide a bond with the portions of said pages opposite thereto whereby to prevent unfolding of those portions of the strip sides which are turned up about the corner edges of the book.
Claim 15
Dependent Claim
135 words
An adhesive binding piece for use in edge binding pages together to form a book-like assembly comprising: a strip of formable substrate material; a relatively thick stripe of heat activated adhesive on said strip extending longitudinally thereof substantially along the strip centerline, said adhesive stripe being comprised of a relatively low tack adhesive; and a relatively thin stripe of heat activated adhesive on said strip on each side of said relatively thick low tack adhesive stripe and in boundary relationship therewith, said relatively thin adhesive stripes being comprised of a relatively high tack adhesive adapted on use of said binding piece to provide a bond with the portions of said pages opposite thereto whereby to prevent unfolding of those portions of the strip sides which are turned up about the corner edges of the book.
Claim 16
Dependent Claim
53 words
The adhesive binding piece according to claim 13 in which the length of said relatively thick low tack adhesive stripe is less than the length of said strip whereby to provide open areas of said strip at each end thereof into which said relatively thick low tack adhesive may flow upon activation thereof.
